This record describes multibeam echosounder data collected on RV Investigator voyage IN2022_V09, titled "Valuing Australia’s new Gascoyne Marine Park." The voyage took place between 0000 November 19, 2022 and 0700 December 19, 2022 (UTC), departing from Fremantle and returning to Fremantle. The Kongsberg EM710 MKII multibeam echosounder was used to acquire seafloor bathymetry and backscatter information and watercolumn backscatter throughout the voyage in areas with water depths shallower than ~800m including areas within the Gascoyne and Ningaloo Marine Park. The EM710 MKII provides a 0.5° by 1° transmit and receive angular resolution respectively. The echosounder's nominal frequency range is from 40 to 100 kHz. Data are stored in *.all raw format for bathymetry and backscatter and *.wcd format for watercolumn backscatter at CSIRO. There are 351 *.all files totaling 58.8 GB of raw bathymetry/backscatter data and 10 *.wcd files totaling 6.97 GB of watercolumn data in this dataset. Sound velocity profiles were applied to this data during data acquisition. Bathymetry data contained in *.all format are corrected for motion and position. GPS tide was computed using the EGM2008 model and applied to the processed data. Processed data has had outliers removed. Processed line data are available in *.gsf and ascii format, and processed bathymetry grids in geotiff format. Additional information regarding this dataset, including further information on processing streams, is contained in the GSM data acquisition and processing report.

This dataset contains catch data for biological specimens collected by Museums Victoria during the RV Investigator voyage IN2022_V09 "Valuing Australia’s new Gascoyne Marine Park", conducted within the Gascoyne Marine Park, Australia, in 2022. The catch data record specimens obtained from sampling operations undertaken to assess the diversity and distribution of fishes and key habitat-forming and mobile marine invertebrates across multiple depth zones and marine park management areas. Catch records include taxonomic identification to the lowest possible level, specimen counts and/or weights where available and are linked to sampling event metadata such as station number, date and time, geographic location, depth, and sampling gear. These data underpin biodiversity assessments and support ongoing research, conservation planning, and management of the Gascoyne Marine Park across its IUCN II, IV, and VI zoning categories.

This catch dataset comprises specimen-based occurrence records collected by the Western Australian Museum from the Indian Ocean during a series of marine research voyages. Specimens were obtained aboard the RV Investigator during voyages IN2021_V04 and IN2022_V08 (Biodiversity Assessment of Australia’s Indian Ocean Territories) and IN2022_V09 (Valuing Australia’s New Gascoyne Marine Park), and aboard the RV Falkor during voyage FK200308 (Illuminating Biodiversity of the Ningaloo Canyons) in 2020. The dataset includes taxonomic identifications and associated collection metadata such as date, geographic location, and voyage information.

This record describes the Acoustic Doppler Current Profiler (ADCP) data collected from the Marine National Facility RV Investigator voyage IN2022_V09, titled: "Valuing Australia’s new Gascoyne Marine Park." The voyage took place between November 19, 2022 and December 19, 2022 (AEST), departing from Fremantle and returning to Fremantle. The ADCP was run for a notable part of the voyage, though it was turned off occasionally to avoid creating interference with the sounders and USBL. ADCP data were collected using the University of Hawaii Data Acquisition System (UHDAS) and post-processed using the Common Ocean Data Access System (CODAS). Documentation for these systems can be found in (Hummon, 2009-2021). Both the RDI Ocean Surveyor 150kHz ADCP and the RDI Ocean Surveyor 75kHz ADCP were run in narrowband mode. Internal triggering was used. The drop keel was set at 1.19m below the waterline for the duration of the voyage. Apart from the gap in the data, due to ADCP being turned on/off, and the usually required quality control data cleaning there were no significant ADCP processing-related issues encountered. To access the full voyage plan and other reports and data associated with this voyage, please see the contact information at the end of this report. This dataset was processed (quality-controlled), and then archived by the CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC).
